Printing via NFC on Officejet Pro 8620 gives error message on mobile phone

I just set up my new Officejet Pro 8620 for the first time. I am trying to print via NFC using a Nexus 5 on 4.4.4. I open the built-in pictures app on the phone and touch the NFC connection spot on the printer. Both devices give an audio que, but I get a message saying something like (it's in Norwegian) "New label created" and then a list of error messages below on the Nexus. Any idea what I can do to get it working?

Cheers, Thorbjørn
